Method, apparatus, and computer product for processing resource change

Abstract

A software RM and a network RM read out information from a system resource DB, and perform a software install or a network setting corresponding to a server group to which a server is to be added on a server in a pool based on read information. When a server included in the server group is failed or when a load on the server group increases, the software RM and the network RM adds the server on which the software install or the network setting is performed to the server group.

1 . A computer-readable recording medium that stores therein a computer program for adding/changing a backup server in a plurality of server groups configured with a plurality of servers, the computer program causing a computer to execute: 
 setting including 
 acquiring setting information, which is information on a setting of a software, a network, and a storage, for a server group, and  
   performing a setting corresponding to the server group on the backup server in advance, based on the setting information; and    adding, when an abnormality occurs in the server group or when a load on the server group increases, the backup server for which the setting is performed at the setting to the server group.    
     
     
         2 . The computer-readable recording medium according to  claim 1 , wherein 
 the setting includes 
 acquiring the setting information for each of the server groups, and  
 performing the setting on the backup server in such a manner that the setting corresponds to each of the server groups, and  
   the adding includes making it possible to add the backup server to any one of the server groups.    
     
     
         3 . The computer-readable recording medium according to  claim 1 , wherein the setting includes 
 incorporating once the backup server into the server group,    performing the setting corresponding to the server group on the backup server, based on the setting information, and    disconnecting the backup server incorporated into the server group from the server group.    
     
     
         4 . The computer-readable recording medium according to  claim 3 , wherein 
 the incorporating includes incorporating the backup server that is disconnected from the server group at the disconnecting into a server group into which a backup server is not incorporated from among the server groups, and    the performing the setting includes performing a setting corresponding to the server group into which the backup server is incorporated on the backup server, based on setting information of the server group into which the backup server is incorporated.    
     
     
         5 . The computer-readable recording medium according to  claim 1 , wherein the computer program further causes the computer to execute: 
 determining, when the backup server is added to the server group at the adding, whether the setting information of the server group is updated; and    resetting, when it is determined that the setting information of the server group is updated at the determining, the backup server based on updated setting information.    
     
     
         6 . A method of adding/changing a backup server in a plurality of server groups configured with a plurality of servers, the method comprising: 
 setting including 
 acquiring setting information, which is information on a setting of a software, a network, and a storage, for a server group, and  
 performing a setting corresponding to the server group on the backup server in advance, based on the setting information; and  
   adding, when an abnormality occurs in the server group or when a load on the server group increases, the backup server for which the setting is performed at the setting to the server group.    
     
     
         7 . The method according to  claim 6 , wherein 
 the setting includes 
 acquiring the setting information for each of the server groups, and  
 performing the setting on the backup server in such a manner that the setting corresponds to each of the server groups, and  
   the adding includes making it possible to add the backup server to any one of the server groups.    
     
     
         8 . The method according to  claim 6 , wherein the setting includes 
 incorporating once the backup server into the server group,    performing the setting corresponding to the server group on the backup server, based on the setting information, and    disconnecting the backup server incorporated into the server group from the server group.    
     
     
         9 . The method according to  claim 8 , wherein 
 the incorporating includes incorporating the backup server that is disconnected from the server group at the disconnecting into a server group into which a backup server is not incorporated from among the server groups, and    the performing the setting includes performing a setting corresponding to the server group into which the backup server is incorporated on the backup server, based on setting information of the server group into which the backup server is incorporated.    
     
     
         10 . The method according to  claim 6 , further comprising: 
 determining, when the backup server is added to the server group at the adding, whether the setting information of the server group is updated; and    resetting, when it is determined that the setting information of the server group is updated at the determining, the backup server based on updated setting information.    
     
     
         11 . An apparatus for adding/changing a backup server in a plurality of server groups configured with a plurality of servers, the apparatus comprising: 
 a setting processing unit that acquires setting information, which is information on a setting of a software, a network, and a storage, for a server group, and performs a setting corresponding to the server group on the backup server in advance, based on the setting information; and    an adding processing unit that adds, when an abnormality occurs in the server group or when a load on the server group increases, the backup server for which the setting is performed by the setting processing unit to the server group.    
     
     
         12 . The apparatus according to  claim 11 , wherein the setting processing unit includes 
 an incorporating unit that incorporates once the backup server into the server group,    a setting unit that performs the setting corresponding to the server group on the backup server, based on the setting information, and    a disconnecting unit that disconnects the backup server incorporated into the server group from the server group.
